Tile-in sinks refer to a type of mounting that requires the tile be installed around the sink. The sink is level with the kitchen counters with this particular type of mounting.
Tile-in sinks are consistent with the standard size of kitchen sinks. A standard sink is 33 inches by 22 inches. Since tile-in kitchen sinks require placing tiles around the sink area and dropping in the sink, sinks can be bigger or smaller than the standard size while still allowing for a tiled-in mounting.
Tile-in sinks come with a distinctive shape. It consists of all straight lines with corners at 90-degree angles. The rim is level with the surrounding counter and tiles are typically square.
Tile-in sinks are often installed in conjunction with tiled countertops. Before the tile is installed, a wood base and sheeting called a "membrane" must first be installed to prepare the countertops. Installers lay a fresh coat of mortar and install the tile in the mortar. The sink is set level with the mortar.
Tile-in sinks provide a few advantages over other types of sinks. The tiled countertops and the tile from the sink are aligned and are not broken up by a rim, so tiled-in sinks have a sense of continuity that other types of sinks lack. Tiles are also easy to keep clean and do not leave water spots behind like other materials. It is also easier to wipe debris on the counters into a tile-in sink than into a self-rimming sink.
Tiles are susceptible to breaking, which can cause you to have to replace chipped tiles. The grout between the tiles easily collects dirt, grime and bacteria so you must be extra vigilant about keeping your tile-in sink clean.
